Claims.

"This invention relates to vehicle wheels and more particularly to wheel structures of the type particularly adapted for use on automobiles.

The invention resides in the provision of a 5 demountable wheel characterized by eflicient means whereby the wheel may be 'easily and quickly mounted on or demounted from an inner hub as the case may be.

The invention together with its objects and advantages will be best understood from a study of the following description taken in connection with'the accompanying drawings wherein:

Figure 1 is an elevational view of the outboard side, of the wheel embodying the features of the present. invention.

Figure 2 is a'detail sectional view taken substantially on the line 2-2 of Fig. 1.

Figure 3 is a view taken substantially on the line 3-3 of Fig. 1 with the hub omitted.

Figure 4 is a detail viewtaken substantially on the line 4-4 of Fig. 2. I

Figure 5 is a fragmentary detail view illustrat- 7 ing the locking plate in an unlocked position.

' Figure 6 is a detail elevational view of the inner hub.

Figure 7 is an elevational view of the locking plate.

Figure 8 is .a detail view'taken substantially on the line 8-8 of Fig. 7. a

Figure 9 is a detail view taken substantially on the line 9-9 of Fig. 8.

Figure 10 is a fragmentary detail sectional view through a portion of the inner hub of the vehicle wheel, the shell portion of the outer hub, and the looking plate in the region of a pocket in the inner hub, a key hole slot in the shell portion of the outer hub and an adjacent bolt and lug, and showingthe locking plate in a substantially un-, locked position.

40 Referring to the drawings by reference nu- H of a vehicular wheel, of the wire'spoke type,' and designated generally by the reference numeral 'W. The outer hub of the wheel and to which the spokes. of the wheel, at one end are secured, include a circular flanged section 5 housing the inner hub H and a smaller section 6 housing the axle spindle.

In accordance with the present invention bolts 1 extend outwardly from the hub section H through openings suitably provided in said hub section and threadedly engaged with the bolts 1 are nuts 8 that have reduced portions 9. Also,

the hub section H adjacent each bolt 1 is formed to provide a pocket or recess In.

The shell portion 5 of the outer hub is provided with an annular series of spaced keyhole slots H, one for each nut 8 and pocket l0. Thus, for example, in mounting the wheel in place, the nuts 8 are first received in the enlarged portion of the keyhole slots II and the hub portion 5 is then rotated in one direction relative to the hub section'H so that the narrow portions of the slot engage the inner reduced end of the nut for securing the wheel in place. To remove the wheel the operation is exactly the reverse tothat just described with regard to the mounting of the wheel- An annular locking plate I4 is provided, and is cooperable with the hub section H for locking the inner end outer hub sections of the wheel together. r

The plate 14 is provided with a circular series a of spaced openings l5 which, as shown, are hexagonal, and are adapted to receive hexagonal portions of the nuts 8.

The plate M on one side thereof and in proximity to the openings I5 is provided with lugs I! which, when the hubsections of the wheel are in final locked position, are received in the recesses Ill through the enlarged end of the slots l I.

Also detachably mounted on and screw threadedly engaged with the hub section 5 are headed studs [6 which serveto secure the locking plate M in mounted position and which are threadedly engaged with the shell 5 of the hub incidental to the mounting thereon of the locking plate M, the studs It being accommodated by openings l8 provided therefor in the locking plate. The openings I8 as best shown in Figure '7 are in the form of arcuate slots so as to permit a shifting of the locking plate I4 relative to the shell section 5 of the hub for looking or releasing the wheel; the bolts l6 and slots l8 also serve as a medium for retaining the hub shell 5 and the locking plate l4 associated with one another at all times to prevent loss or misplacement of the locking plate.

The wheel structure as above described is more fully completely set out and claimed in Patent No. 2,008,330 granted'to me under date of July 16, 1935, and entitled Automobile wheel.

The present application is particularly concerned with improved means for positively securing the locking plate M in position and the provision of such means may be also utilized in the nature of handle means to facilitate proper placement and displacement of the looking plate l4 incidental to a mounting or demounting of the wheel.

Thus in accordance with this invention the hub section H is provided with diametrically disposed pins 20 having reduced ends threadedly engaged with said hub section.

To accommodate the pins 20 hub section 5 is provided with slots l9 and the locking plate I4 is provided with arcuate slots 2!, and positioned adjacent each slot 2| is a nut 22 that has a swivel connection with the plate I4, this connection being provided through the medium of a flange 22 on one end of the nut engaged by arcuate jaw members 24 arranged in pairs and. secured to the plate M at opposite sides'of the slot 2| in any suitable manner as indicated generally at 25. Thus it will be seen that the nut 22 is mounted on the plate for rotativemovement and thereby is readily threadedly engaged with the stem 20 for drawing the plate I 4 into final locking position. To facilitate the'threading or unthreading of the-nut 22 relative to its pin 29 said nut is provided with suitable handle means 25.

Also to secure the nut 22 against casual unthreading said'nut, intermediate its ends is provided with a series of ratchet teeth 21 formed on the periphery thereof and normally engaged by dog 28 pivotally mounted'on one of the jaws 24 and normally urged into engagement with the ratchet teeth through the medium of a spring 29.

For releasably holding the dog 28 out of engagement with they ratchet teeth to thereby permit an unscrewing of the nut 22 there is also provided a suitable keeper hook 30 that may be readily engaged with the end of the dog 28 connected with the spring-29 when the dog has been swung out of engagement from the teeth-21.

From the above it will thus be seen that to mount the wheel the hub shell 5 is first positioned to aline the largest ends of 'theslots H with the bolts 8, whereupon the bolts8 are received within the largest ends of the slots II: and the hub shell 5 then rotated to the position shown in Figure 5 for engaging the reduced ends of'the nuts 8 in the narrow portion of the slots II. This will also result in alinement of the larger ends-of the slots I lwith the recesses I as shown in Figure 5.

The locking plate 14 which is carried by the hub shell through the medium of the aforementioned headed studs IS in a manner 'tobe free to move axially toward or away from the shell member 5 or to rotate toward-the right or toward the left relative to the hub shell 5, is first rotated to a position to-aline the openings therein with the bolts 8-and the studs ll thereon with the-alined pockets I0 and enlarged ends of slots H. -When such alinement is obtained the plate- I4 is then moved inwardly into contact with theadjacent portion of the hub shell 5, the hexagonal portions of the nuts 8 ment of the locking plate It inwardly-into locking position is accomplished by threading the nuts 22 home on the pins as is thought to be apparent.

It will thus be seen that the. parts are now all locked in assembled positionand the mount- 1 ing of the wheel-is completed. Separation of the assembledparts is effectively prevented by the engagement of the dogs 28 with the ratchet teeth 2'! on the nuts 22 as thought to be apparent, such dog and ratchet means serving to effectively prevent unscrewing of the nuts 22 until the dogs are positively moved out of engagement with the ratchet teeth as is also thought to be apparent.

Manifestly to demount the wheel the operation above described is reversed.

Having thus described my invention, what I claim as new is:

1. In a wheel assembly of the character described having an inner fixed'hub structure and an outer hub shell mounted on the inner hub structure an annular plate on the side of the outer shell opposite to the inner hub structure and movable to secure the shell in place on the inner hub structure, threaded studs projecting from said inner hub structure and through said 'hub shell, and said plate having openings through which said studs extend, nuts threadedly engaging said studs and engaging the plate to move the latter into position for securing'the shell in place, each nut being'providedon its circumference with ratchet teeth, and adog pivotally mounted on the plate and engageable with the ratchet teeth to secure the nut against retrograde movement.
